ktor-server-cio ignores deployment.host

[meoyawn]

Ktor Version and Engine Used (client or server and name)
1.2.5, server, ktor-server-cio

Describe the bug

my application.conf:

ktor {
    application {
        modules = [ adeln.MainKt.module ]
    }
    deployment {
        host = "127.0.0.1"
        port = 8080
    }
}

When I run netstat -plnt:

With ktor-server-cio deployment.host is ignored and my server is accessible externally:

tcp6       0      0 :::8080                 :::*                    LISTEN      24413/java          

To Reproduce

1. Use my application conf
2. Launch the server using ktor-server-cio
3. Run netstat -plnt and see that deployment.host is ignored

Expected behavior
With ktor-server-netty deployment.host is applied correctly:

tcp6       0      0 127.0.0.1:8080          :::*                    LISTEN      24978/java
